Some Formulas are derived by means of experimentation. Among these are the formulas discovered by pascal, Galileo and Archimedes. They are called empirical formulas.
Examples of Empirical formulas:
1.1 a formula for changing temperature from Fahrenheit to centigrade.
2. a formula showing the relation of weights on a balance with the lengths of its arms.
3. -a formula used in finding electrical power.
4.a formula for finding work done in foot pounds.
5. an ohms law, a formula for finding I, the number of amperes of electric current , E, the electromotive force in volts, and R, the resistance in ohms.
6. a formula for finding the distance covered by falling bodies.
Examples of Empirical formulas:
1.1 a formula for changing temperature from Fahrenheit to centigrade.
But what about empirical formula which we use in power system?
ReplyDeleteBot what is about empirical formula which used in power system analysis..?
